Line segment AB has a length of 5 units. It is translated 3 units to the right on a coordinate plane to obtain line segment A'B'. What is the length of A'B'?

2 units
3 units
4 units
5 units

i think 3 because it said

It is translated 3 units to the right on a coordinate plane to obtain line segment

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
